Geraldine Holm Hoch

Geraldine Holm graduated in 1943 with a degree in both chemistry and math (double major). Fresh out of college she worked for Pratt & Whitney Aircraft Engine Corp in Kansas City, Missouri, as an electrochemist in research and development supporting the Pratt & Whitney R-4360 Wasp Major aircraft engine which saw service at the end of World War II in the retro-fitted models of the Boeing B-29 Superfortress and later used on the Boeing B-50 "Lucky Lady".

She then moved to Southern California for career opportunities where she was employed in 1948 with Northrop Grumman (then called Northrop Aviation) in Los Angeles. She was one of the first female research chemists employed there. She worked alongside Jack Northrop in research and development.^[1]

At Northrop, she worked on the SM-62 Snark missile project, an intercontinental missile program that resulted in the development of one of the world's most complex digital computers and astronomical guidance systems.^[1][2]

In 1950, Gerry moved to Kansas to start a family. From 1950 to 1952 she worked at Bendix Corporation as chemical engineer and handled research and development in nickel electroforming. She then joined Midwest Research Institute and furthered her research as an electrochemist. She designed the electroforming facility to produce cylindrical shells for missile body wind tunnel studies. At MRIGlobal, she became aware of the gender paygap. Despite working on materials science for the space program, she was paid as an administrator.

In 1965, she returned to California and accepted a position as a research chemist for Lockheed Martin, (aka Lockheed Calif Company, Rye Canyon Research Division) where she worked in metallurgy.^[1] Hoch developed and patented new ways to prevent corrosion.^[1][3][4]

Works at Northrop Grumman credit her corrosion prevention efforts in the design of the fuselage panels for Boeing 747s.

She presented her work at the 1971 NATO conference held in Brussels, Belgium.^[1]

Gerry developed cancer but continued to work at Lockheed while she was unwell.^[1]

Geraldine Holm met her future husband, Harry Edward Hoch, an industrial engineer, in a carpool at work. They raised 3 children who all became engineers. She was a member Business and Professional Women's Foundation in San Fernando Valley, California. She died of cancer on May 3, 1973, in Los Angeles.^[5]
